Treatment bed



FIG. 1 is a perspective view of my new design;

FIG. 2 is a top plan view;

FIG. 3 is a front elevational view;

FIG. 4 is a right end elevational view; and,

FIG. 5 is a bottom plan view.

The left side elevational view is a mirror image of the right end elevational view. The rear elevational view is a mirror image of the front elevational view. 

I claim the ornamental design for a treatment bed, as shown and described.
